What is the best approach to make PCM and TCM to learn anything ? I am not kidding, I just had my TSB update done and I see now :

- the rpms at idle are greater and the car "shakes" as never before
- from full stop, pressing on the pedal feels like the car has no power

It does keep the rpms before shifting, but... I think the TSB for me is an downgrade rather than an upgrade right now. On the file there is written that the drive cycle has been performed after the update... Really ?!?

P.S. If I want to repeat the drive cycle myself, how long should I unplug the battery before doing it ?

This was after 12-1-4? Not sure how long the battery needs to be disconnected (somewhere in here is someone who did just that, but I can't find it quickly), but I'd think 5 minutes or so should be enough if that actually erases the "learning" memory.
